Characterization of reservoir deliverability is fundamental in economic development of any field. In the Bakken this understanding is particularly important because of the reliance on massive hydraulic fracture stimulation. Determining well deliverability potential, by conventional drill stem tests (DST) or traditional Wireline Formation Tester (WFT) methods has led to mixed success in Bakken. On the other hand, the mini-DST has definitely increased the reliability and success rate of pressure transient tests.
The interpretation of mini-DST drawdown and buildup pressure responses from each tested interval can provide an assessment of the relative flow potential of each formation. The analyses and observations have provided very useful insight into a better understanding of the near-wellbore flow mechanism in Bakken. In this talk, the operation of mini-DST equipment, test interpretation procedure and field examples to demonstrate the effectiveness of such mini-tests will be shown. The entire experience can also serve as a basis for test design in similar low-permeability reservoirs around the world.
Basak Kurtoglu is a Reservoir Engineer at Marathon Oil Company and a PhD candidate at Colorado School of Mines, researching on enhanced oil recovery in unconventional reservoirs. She received a MS degree in petroleum engineering from the Colorado School of Mines in 2008. She has published on topic in reservoir simulation, reservoir management and pressure transient analysis. She has served on several SPE committees. She serves as a member in the SPE Forum Series Implementation Committee and the SPE Reservoir Description and Dynamics Advisory Committee.
